Advanced AI Prompt for Blurred-to-Sharp Focus Reveal

Act as a Master Cinematographer. Design a suspenseful 3-second visual hook relying entirely on a dramatic 'Rack Focus' technique. The opening frame must feature extreme, creamy bokeh completely obfuscating the [SUBJECT] in the foreground, rendering them an unrecognizable blob of color. Over a precise [SPEED_OF_FOCUS] duration (e.g., a rapid 0.8s snap or a slow 2.5s creep), mechanically pull focus to reveal the [SUBJECT] in razor-sharp clarity, while simultaneously blurring out the [BACKGROUND_CONTEXT]. Specify the required lens aperture (e.g., f/1.2 or f/1.4) and dictate the exact backlighting setup required to make the subject's edges 'pop' the millisecond they hit the focal plane. This exploits the brain's biological mandate to resolve blurry anomalies.
